From 37a13e78e017c31fbb98a148b54c2552dc08d788 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 16 Jul 2015 16:56:25 +0530 Subject: [PATCH] powerpc/time: Migrate to new 'set-state' interface Migrate powerpc driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. We weren't doing anything in ->set_mode(ONSHOT) and so set_state_oneshot() isn't implemented.
